Every time you pop in an usb stick android creates an backup folder on it. Therefore i tried to write my own app with the same permission and call 'su' which did however not work out (even if I use the same namespace org.droidtv.?)ĩ. The Manifest also shows this strange '.tv_power_system_access' permission.

If this is no obsolete debug code (i was not able to trigger this part yet) than there could be a 'su' inside /sbin. The settings-app calls the 'su' command inside of CSMActivity. But you need to be really careful with this, i already managed to break booting without changing something important.Ĩ. However there is also the real service menu (062?96i) which could be used for much more things. There is a Customer-Service-Menu at “123654” which contains read only information about the current firmware and so one. press and hold the joypad on the backside of the TV downwardsħ.

The recovery menu which could be used to install a 'new' firmware if the device does not boot properly could be reached via the following steps: There are 3 SGUID and 1 SUID binaries (visible):Ħ. data/anr: davlik crash-dumps of android applicationsĥ. data/debugdump: stack-traces, process-lists, short memory excerpts based on crashes of the native binaries (could be very helpful for exploiting)

There are two world-readable directories containing very interesting information: Maybe someone good at kernel-drivers could take a look?Ĥ. The trcext module seems to be very interesting as a short look with a disassembler revealed that it might be able to read and manipulate process memory of any process. Kernel version: Linux version 3.4.70+ (gcc version 4.6.x-google 20120106 (prerelease) (GCC) ) #1 SMP PREEMPT Fri Nov 14 01:52: The current and some older firmware files could be downloaded at philips_samipupu_com (thanks for hosting) : content of /system (ext4-img)į: content of /firmware (ext4-img)īackEndBin.zip, EdidBin.zip, fpgaUhdBin.zip, RougeBin.zip: different binary files - supposedly firmware for these componentsĪs you see I was not able to extract the most interesting part (kernel + ramdisk) - Hopefully some android experts could help! User_setting.zip: content of /user_setting Tzk_: ? maybe recovery (unknown file format)

CHANSORT PHILIPS ARCHIVE

The decrypted firmware archive contains the following files:ī: kernel + initrd + ramdisk (unknown file format)īootloader.zip: bootloader (unknown file format) Maybe mirroring this paste and the source would be a good idea (Google for the HASH if link is down) Source-Code: attachment or pastebin_com / z3nA2r3J the encryption key is generated via 'EVP_BytesToKey' using only the first 127 byte of the keyfile + an eight byte salt found near the beginning of every input file Some interesting details about the used cryptography: It was created via reverse-engineering the 'upgrade.bin' arm-file (thanks for the trace, snoerenberg). I wrote a tool to decrypt the official firmware. Hell I bought this expensive device and have no idea and can't nearly control what is sent to Philips nor Google.ġ. I like to develop at system base, use the underlying linux tools and most important check what the manufacturer does (behind my back) in my own living room.

CHANSORT PHILIPS SOFTWARE

As those are often forcing the users into their own 'crappy' software without given them any chance to escape. You might ask what those extended privileges should be good for? Well in my eyes android - a project available as open source with uncountable possibilities for developers and users - should not be closed down by profit oriented manufacturers. Unluckily without the final breakthrough - but at least I found out some very interesting details. I already spent plenty of time researching the internals of the device in order to get root privileges. So as you decided to ignore my warning, here we go: If you post about vulnerabilities and stuff better cover your ass - who knows what the legal department of philips thinks about your cool stuff. For every one else: don't blame philips if you brick your device -> think before actually trying. WARNING: don't look at the following information nor try to use any of it if you have no clue about linux or android as it is most likely that you are going to break your expensive gadget.
